LEWIS O. JOHNSON AND WILLIAM L. WEST, OF MARTINSVILLE, OHIO.

IMPROVEMENT IN DITCHlNG-MACHINES.

Specjicationforming part of Letters Patent No. 76,6110, dated April 25, 1876 application filed March 25, 1876.

To all whom it may concern:

Be it knowuthat we, LEWIS G. JOHNSON and WM. L. WEST, of Martinsville, in the county of Clinton and State of Ohio, have invented a new and valuable Improvement in Ditching-Maehines; and we do herebydeclare that the following is a full, clear, and exact description ofthe construction and operation frame of the machine, mounted upon front and rear axles B B', with wheels O O and C C respectively.

Under the center-beam A1 of the frame is suspended the plow-beam D, with plow Dsecured thereto. At the front end ot' the plowbeam D is a loop or soeket,a,which surrounds a shaft or bar, b, depending from the beam Al.

From near the front end of the plow-beam Y D extends a perforated bar, d, up through a niortise in the beam A1, and from the rear portion ot' said plow-beam extend two similar perforated bars, d df, through loops e at the side of the beam A1, said perforated bars be ing all held at any desired height by pins t' i.

' For' adjusting the plow an eccentric lever, E, is pivoted above the beam A1 between the bars d d', as shown.- By this lever ,working against the top of the beam A1 the plow can easily be raised, as required.

From the lower end of the plow-beam D extends la shoe, Gr, on top of which is mountl ed a roller, f. Around this roller passes an endless apron, H, which also passes around a roller, f', mounted under a beam, I, in an upright frame, A2, at the rear end of the main frame. the side pieces of the frame `A2, and is adjusted up or down, to regulate the apron so as to correspond with the adjustment of the plow. The beam I is held by a perforated bar, J, passing upward from it and through a mortise in the top bar of the frame A2. lo this beam is also attached an inclined conductor, K, as shown.

The plow, with its cutters h, as shown, cuts the earth and delivers it on the apron, which carries it up into the spout or conductor K, and this delivers it at the side of the ditch.

The apron H in a full-sized machine will be composed of a series of buckets connected together, and it is run by belt from a pulley, L, on a counter-shaft, M, and this shaft is rotated by belt from the axle B'.

The pulley L on the counter shaft M is movable thereon by means of a lever, N, so as to be thrown iu and out of gear, as required. Instead of belts and pulleys, suitable gearing may be arranged for operating the apron.

P represents a rolling colter, with blades p, mounted in a frame, It, and adjustably connected to the beam A1 in front of the plow.

by Letters Patent, is-

In a ditching-machine, the combination of the plow-beam D, with loop a, the barb, beam A1, perforated bars d d', and eccentric lever E,substantially as and for the purpose set forth. p

In testimony that we claim the above we have hereunto subscribed our names in the presence of two witnesses.
